Description
Technical field
It is more particularly to a kind of to be used for anti-inorganic matter fouling anti-soil the present invention relates to a kind of composition for ant-scaling anti-soil
Composition, belong to field of novel.
Background technology
Production, Treatment of Industrial Water, ore dressing recirculated water, ore dressing sewage disposal, Industrial Waste Water Treatments, industrial water circulation in oil field
During utilization, due to containing different types of inorganic ions in the aqueous solution, under certain condition, usually occur that fouling is asked
Topic, it is common such as calcium carbonate scale, calcium sulfate scale, when amount of scale buildup is few, fluid flow can be reduced, pipelined liquid energy consumption increases
Plus, pipeline even is blocked when fouling is serious, causes directly stopping production, causes larger economic loss, when dirty layer exceedes certain thickness
When, it is necessary to remove dirty layer, dirty layer is removed repeatedly not only influences normal production, increase production cost, can also reduce pipeline, equipment
Service life.If inorganic ions fouling can be prevented fundamentally, can greatly reduce naturally due to fouling produce it is a series of
Problem, physical method and chemical method can be divided into by preventing the method for inorganic ions fouling, such as using crystal seed antiscale, electric field antiscale,
Frequency conversion antiscaling etc., these belong to physical method, and the effect of these method scale inhibitions is limited；Chemical method is mainly addition antisludging agent,
Antisludging agent is the medicament that can control to produce incrustation scale and dirt, is mainly divided to two classes, a class is dispersant, than colloid on general yardstick
Grain is much smaller, the material of linear structure, most commonly lignin, tannin, artificial synthesized acrylic acid again on molecular structure
Copolymer, copolymer-maleic anhydride etc., another kind of is containing can form special coordinate bond with metal ion in chelating agent, molecule
How rare group, such as hydroxyl, sulfydryl, sulfonic group, phosphate, carboxylic acid group, its addition is with containing metal ion in the aqueous solution
Close.The advantage of addition antisludging agent is that using more convenient, general addition is few, but needs constantly addition the problem of exist, because
For whether dispersant or chelating agent, always there is certain metering ratio with metal ion, although can prevent the formation of dirt, but
New chemical substance is always generated in solution, final or antisludging agent that will be to addition and the novel substance progress of metal ion generation
Processing, another drawback is that different ions require the different types of antisludging agent of addition, thus it is a kind of it is general, can prevent
Different kinds of ions generates the antisludging agent of inorganic scale, and water quality is different, and the composition of antisludging agent is also differed, the production process of the 3rd antisludging agent
It is still a production process with specific function chemicals, however it remains the potential safety hazard, the 4th such as burning, blast, pollution
Antisludging agent still needs with ionogenic novel substance to be handled, however it remains pollution hidden trouble；The use of new material is to solve nothing
The fouling of machine thing and the effective way of dirt, such as using nonpolar polytetrafluoroethylene (PTFE), polyethylene, polypropylene, ethylene propylene copolymer
In the materials such as thing, these materials, ant-scaling effect most preferably polytetrafluoroethylene (PTFE), but polytetrafluoroethylene (PTFE) is expensive in itself, limit
Make it to use on a large scale, ultra-high molecular weight polyethylene physical and mechanical properties is excellent, but processing difficulties, to reduce cost, can be with
These non-polar materials and metal material are combined, steel lining polytetrafluoroethylene (PTFE) pipeline, steel lining polytetrafluoroethylcontainer container etc. is made,
It can be made steel frame polyethylene compound pipe road or clad vessel, steel skeleton polypropylene pipe or container etc., but due to metal material
The difference of material and high-molecular compound physical and mechanical properties, processing difficulties, steel modeling adhesion is poor in addition, easily layering.
It is to prevent one of method of fouling to prepare ant-scaling coating or coating.CN1614282 discloses a kind of macromolecule and glued
The composite pipe of elastomeric material, is made up of shell and liner, and the shell is common steel tube or glass reinforced plastic pipe, and the liner is
Polymer viscoelastic material, shell and liner bonding are integrated.

Open and silica coating is included in the heat exchanger plate of ant-scaling property；CN102337049A discloses a kind of aqueous medium heat transmission equipment and used
Anticorrosion ant-scaling coating and preparation method thereof.The coating uses nano titanium powder, pretreating agent, epoxy resin, acrylic acid, bis-phenol
S types epoxy resin or glycidyl ester epoxy resin or glycidyl amine epoxy resin, organic solvent, amido silicon oil have
Machine fluorine reagent, distilled water, are pre-processed, prepared by epoxy resin modification, three main technological steps of coating preparation by nano titanium powder
Form, with anticorrosion, ant-scaling, the advantages of effectively improving heat transfer efficiency and the service life of heat exchanger.
With the development of chemical industry, the improvement of production technology is increasingly enriched with nonpolar solid matter species,
In addition to above-mentioned polytetrafluoroethylene (PTFE), polyethylene, polypropylene, ethylene propylene copolymer, Fischer-Tropsch wax, microwax, stone common are
Oleoresin, Tissuemat E, polypropylene wax etc..
Fischer-Tropsch wax is carbon original in the solid-state hydrocarbon mixture based on n-alkane obtained by F- T synthesis, n-alkane
Subnumber is more, and fusing point is higher；The mixture that microwax is made up of n-alkane, isoparaffin and cycloalkane, with pertroleum wax phase
Than the large percentage that isohydrocarbon and cycloalkane are accounted for, the ratio shared by n-alkane is smaller, in general, the alkane in microwax
Molecular weight is larger, and carbon atom distribution is wider than paraffin in alkane, and hydrogen-carbon ratio is 1.85 or so, and microwax hardness is small, pliability
It is good, tend to Plastic Flow during stress at a certain temperature, ductility is big, flexible good, gel strength is big, adhesiveness and protective
It is good.Petropols are the oligomer that the hydro carbons accessory substance obtained in hydrocarbon cracking process is obtained by polymerisation, according to by-product
